CLIP FOR LOCOMOTlVE-SPRINGS.

SPECIFICATION forming part of Letters Patent No. 325,201, dated August 25, 1885.

Application filed July 29, 1884. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM EVANS, a citizen of the United States, residing at Phila delphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Clips for the Ends of Locomotive-Sprin gs, of which the following is a specification.

It has been the practice heretofore in forming clips for locomotive springs to take a piece of steel of sufficient size to form the clip, scarf the end, rivet said piece to a bar of steel, heat to the welding-point, and weld the two pieces on the anvil by hand.

The object of this invention is to manufacture clips cheaper and more expeditiously and the invention relates, mainly, to rolling a heated bar of steel through a pair of rolls of suitable size and shape to form the taper, the scarf on one end, and the cove on one of the surfaces for the reception of the link of the spring.

My invention further embodies a clip cut by any suitable means from the rolled bar, and provided with weldingtlanges upon each edge of its lower surface, extending throughout the length of the clip, between which flanges, and contiguous to the under surface, is placed the end of a bar of steel forming the outer end of the upper or main plate of the semi-elliptic spring, the parts to be united by heating and welding.

In the accompanying drawings, which make a part of this specification, Figure 1 is a side elevation of the upper. die, A, and pair of lower dies, B B, the bed-plate (J, and rolled bar D in position ready to be cut into clips. Fig. 2 is a plan view of the lower dies, B B, and bedplate 0. Fig. 3 is an end view of the same, with the rolled bar thereon. Fig. 4 is an end elevation, on an enlarged scale, of the rolled bar D. Fig. 5 is a face view of the underside of the clip E. Fig. 6 is an end elevation of the same. Fig. 7 is a longitudinal section of a finished clip, E, ready for welding to the bar H. Fig. 8 is a side elevation of the lower part of the upper die or punch, A. Fig. 9 is a like view of one of the lower dies,B. Fig. 10 is a side elevation of the finished clip E in position on the bar of steel II. Fig. 11 is an end view of the same. Fig. 12 is a like view showing the flanges a a slightly hammered down. Fig. 13 is a side elevation of a welded end of a spring. Fig. ii is a crosssection of the same,

Like letters of reference in all the figures indicate the same parts.

In the prelimary operation a bar of steel of any length is heated and run between a pair of rolls, said bar when completed assuming the outline shown in Fig. 4. The bar D is again heated, placed upon the lower die 13, with its end slightly projecting over upon the die B, suiiiciently far to form one flange of the clip 1). The upper die or punch, A, is brought into operation and the clip cut off, at the same time the flanges a. a are dragged up on the sides of the clip to form sufficient metal for welding the clip to the bar of steel H. The dies B B rest upon the blocks J J, and have adovetailed connection therewith. The blocks J J have a lateral movement on the bedplate U, and are held firmly in any desired position by the screw-bolts K K, passing into them through the slots 1) in the bedplate.

When it is desired to alter the width of clips to be cut, the said bolts K K are loosened, and the set-screws L L, which have hearings in the upwardly-proieeting flanges N N of the bed-plate, are turned to the right or left, as the case may be, to increase or decrease the space between the lower dies B B, and said dies are then moved inward or outward the requisite space, and the screw-bolts again tightened. After the formation of the flanged clip 1*], it is placed upon a flat bar of steel, H, as shown in Figs. 10, 11, and 12, the flanges a, a serving to hold the pieces securely together, a heat taken, and the parts securely welded. The flanges, however, are mainly for the purpose of providing sufficient metal to unite with the bar H and form a perfect weld. All of the dies are rounded at the corners, to prevent giving too sharp an angle on the clip and to allow freedom of actionin the punching operation.

I claim as my invention-- 1. A tapered bar of metal 1), rolled and searfed into the shape shown and described, for forming clips for the backs of locomotivesprings.

2. The clip E, provided with the weldingflanges a a, substantially as shown and described.

WILLIAM EVANS.
